How can I get the information about a particular column of a table by MySQL DESCRIBE statement?
As we know that DESCRIBE statement will provide the information/structure of the whole table. With the help of DESCRIBE statement along with table name and the column name, we can get the information about that column.
Syntax
DESCRIBE table_name col_name;
Example1
mysql> Describe employee ID; +-------+---------+------+-----+---------+----------------+ | Field | Type | Null | Key | Default | Extra | +-------+---------+------+-----+---------+----------------+ | ID | int(11) | NO | PRI | NULL | auto_increment | +-------+---------+------+-----+---------+----------------+ 1 row in set (0.11 sec)
The query above will give the information about the column ‘ID’ of a table named ‘employee’.
Example2
mysql> Describe employee name; +-------+-------------+------+-----+---------+---------+ | Field | Type | Null | Key | Default | Extra | +-------+-------------+------+-----+---------+---------+ | Name | varchar(20) | YES | | NULL | | +-------+-------------+------+-----+---------+---------+ 1 row in set (0.03 sec)
The query above will give the information about the other column ‘Name’ of a table named ‘employee'.
